ABSTRACT:
A blown-in fibrous insulation is provided in a substantially homogenous-density form. A foamed material in its foamed state is mixed with already-lofted fibrous particles and the mixture is blown into a desired space. The foam acts to maintain the fibrous particle loft during impaction from subsequent applications of the insulation material or from the weight of insulation material above. The foam preferably contains an adhesive material which sets or cures to maintain the fiber loft by the time the foam material dries and dissipates. A nozzle designed to provide the described mixing of materials and to avoid backflow and consequent clogging or plugging is provided.
